LAMP-HOLDER.

Specification of Letters Patent.

Application filed December 26, 1914. Serial No. 879,039.

' of which the following is a specificat This invention relates to that class of lamp holders which are mainly employed for supporting the lamps of vehicles, for instance, automobiles and carriages.

The objects of the invention are to provide a holder of simple construction which, while permitting the lamp to be readily applied to the supporting post and removed therefrom, will securely hold thelamp stationarily on the post against accidental detachment without the necessity for a set screw or other fastening device such as heretofore used, which requires manipulation to fasten thela'mp upon the post.

In the accompanying drawings: Figure 1 is a side elevation, on a reduced scale, of a lamp holder embodying the invention. Fig. 2 is a plan view thereof. Fig. 3 is a vertical sectional elevation, full size, thereof. Fig. 4 is a transverse sectional elevation thereof in line 44, Fig. 3. Fig. 5 is a plan. view, partly in section, on line 5-5, Fig. 8. Fig. 6 is a fragmentary pers ective view of the supporting post. Fig. is a side elevation, on a reduced scale, of a holder of slightly modified construction. Fig. 8 is a plan thereof. Fig. 9 is a plan view, full size, of the post thereof. Fig. 10 is a reduced plan of the socket thereof. Fig. 11 is a. fragmentary perspectiveview of the post thereof. Fig. 12 is a side elevation, reduced, of another modified construction of the holder. Fig. 18 is a perspective view of the post thereof. Fig. 14 is a. reduced plan of this holder.

Referring first to the construction shown in Figs. 1 to 6: A represents a portion of a lamp, which may be of any suitable construction, B an upright post which is secured to the automobile, carriage or other vehicle or structure to which the lamp is to be applied, and C an upright socket which is secured on the lamp and by which the lamp is supported on the post B. The post is provided with a horizontal bracket portion D which is provided with any suitable means, for instance, a screw clamp d of ordinary construction, for securing it on the vehicle or supporting structure. The post B and bracket portion D are preferably formed from a blank or piece of sheet metal, the end portion of the blank which forms the post extending upwardly above the bracket portion D and being bent toone side from the bracket portion 'to produce the post which, as shown, is semi-circular in Patented M y 30, 1916.

cross section and tapers upwardly somewhat. E represents a spring tongue or detent on the upper end portion of the post for releasably retaining the socket on the post. This spring tongue is formed by slitting the end portion of the post longitudinally and bending outwardly a portion of the wall of the post. An outwardly pro,- truding hump e is formed on the free end of the spring tongue having a rounded or beveled' outer face. The socket C shown consists of a hollow or cupped part, preferably made of sheet metal and secured to the lamp in any suitable way, and having alined holes f and f, respectively, in the top and bottom walls thereof to receive the post B.

The edge of the upper hole is notched at one side at f to receive the spring tongue E on the post. When applying the lamp to the post the socket C is slipped on the post with the notch f in alinement with the spring tongue E on the post and is pressed downwardly, causing'the hump e on the spring tongue to pass through the notchf and snap outwardly over the upper edge thereof, the beveled or rounded face of the hump 6 enabling this action. The socket is thus retained on the post against accidental detachment, and the engagement of the spring tongue in the notch f also prevents the socket from turning on the post. As the holes f and f are of a size to respectively fit the portions of the post located therein, the lamp is held very securely and rigidly on the post and prevented from rattling. The lamp can, however, be readily detached by simply pulling the socket forcibly off of the post against the holding action of the spring tongue.

end of the post with the spring tongue to be readily passed through it. A reinforcing block 9 having a screw-threaded hole 9' therein is secured in the outer part of the socket shown to enable the lamp,to be secured by a set screw on posts of the ordinary form, and so that the user can, if he de- The bottom-hole f of the socket is large enough to allow the upper sires, use a set screw as an additional optional means for fastening the lamp on the post B. The set screw is not, however, required in the holder described, as the spring tongue securely holds the lamp on the post.

Figs. 7 to 11 show a holder of slightly modified construction in which the post B is provided with two spring tongues E at its opposite edges adapted to cooperate with two notches h in the top hole of the socket C. These tongues operate like the single tongue in the first construction to retain the socket on the post and prevent it from turning thereon. In this construction the post is formed so that its convex side faces inwardly or toward the vehicle instead of outwardly, as in the first construction.-

In the holder shown in Figs. 12 to 14, the post B is provided with a single spring tongue E is in the first construction described, but the post is of difierent shape, being relatively broad and but slightly bowed in cross section, and the socket C is of correspondingly different shape. The spring tongue cooperates with av notch z in the top hole of the socket, as in the other constructions, to retain the socket on the post.

I claim as my invention:

1. Theco-mbination 01" a supporting post provided with a longitudinal springdetent, and a supporting socket removably mounted on said post, said socket having a hole into Copies of this patent may be obtained for which said post extends and a notch in the edge'of said hole into which said detent is adapted to spring to retain the socket on the post.

2. The combination of a supporting post provided with a longitudinal spring detent, and a supporting socket removably mounted on said post, said socket having a hole into which-said post extends and a notch in the edge of said hole into which said detent is adapted to extend, said detent having a projection adapted to snap over the edge of said notch to retain the socket on the post.

3. The combination of a supporting device comprising a bracket portion and a sheet metal post which is curved in cross section and provided with a spring detent formed by an integral portion of the wall of said post, and a socket removably mounted on said post, said socket having a hole into which said post extends with the longitudinal edges of the post engaging one side of the hole and the convex face of the post engaging the opposite side of the hole, said detent engaging one edge of the hole to retain the socketon the post. 7 Witness my hand in the presence of two subscribing witnesses.
